HTML markup errors and warnings
(Rescan now...)
Errors:
Obsolete doctype. Expected “<!DOCTYPE html>”.
Internal encoding declaration “iso-8859-1” disagrees with the actual encoding of the document (“utf-8”).
Bad value “text/html; charset=ISO-8859-1” for attribute “content” on element “meta”: “iso-8859-1” is not a preferred encoding name. The preferred label for this encoding is “windows-1252”.
Bad value “Content-Script-Type” for attribute “http-equiv” on element “meta”.
Bad value “Content-Style-Type” for attribute “http-equiv” on element “meta”.
When the attribute “xml:lang” in no namespace is specified, the element must also have the attribute “lang” present with the same value.
Bad value “schema.DC” for attribute “rel” on element “link”: The string “schema.DC” is not a registered keyword.
The “scheme” attribute on the “meta” element is obsolete. Use only one scheme per field, or make the scheme declaration part of the value.
An “img” element must have an “alt” attribute, except under certain conditions. For details, consult guidance on providing text alternatives for images.
Warnings:
The “border” attribute is obsolete. Consider specifying “img { border: 0; }” in CSS instead.
